> Ignacio, I would like to take this opportunity and inform you of a bug in
> AWS. In the past, I had tried many times loading a trained classifier into
> AWS that used a reduced feature vector (after attribute selection in weka
> explorer). The classifiers would load successfully, but after feature
> calculation the classifier would fail/crash to classify the image(s).
> Today, after Kota's suggestion, I accidentally found that if any of the
> "Structure" features exist in the final feature vector will cause the
> classifier to crash when applying the classification to the images. These
> classifiers are working normally, though, when applied within the weka
> explorer.
>
> I am attaching the corresponding log file. After the last lines are logged
> a pop up message appears saying "Could not apply Classifier!". I have the
> impression, but I cannot confirm that this might happen to classifiers with
> non-reduced feature vectors as long as "Structure" and maybe "Entropy"
> features are used. This issue has been bugging me for some time now and I
> have made all sorts of workarounds to try to avoid it. I hope you can
> resolve it.
